CLARIFICATIONS: This project must be completed no later than is October 5, 07. This is a firm fixed date.. Contractor shall disregard Note # on HM drawings and notes on Mechanical drawings calling for horizontal HW S&R piping to be installed in pipe enclosures. New horizontal piping shall run exposed and insulated with PVC jacketing as noted in New Work Note # on Mechanical drawings to match existing piping that is being removed. Insulated piping located within the new vertical pipe chases does not require PVC jacketing but shall be insulated per specifications. Painting scope clarifications. The contractor shall paint all existing walls floor to ceiling in all closets receiving new vertical pipe chases applying two coats of paint on existing walls and using primer coat on all new GWB for new chases. Contractor shall repair all walls at attachment points where existing radiators are being replaced per A7 below then paint walls floor to ceiling to match existing adjacent wall colors applying two coats of paint.. Updated Wage Rate are attached QUESTIONS: Q. Can you drill into the wall under current regulations? A. Drilling into wall to be performed in compliance with Section 08. Drilling work practices are spelled out in Part. B of Section 08. Section 08 outlines the training and licensing required of the Contractor performing drilling into wallboard. Q. Is tenant furniture movement included in the contract? A. Yes, please see specification section 0000 B.. Q. Will you publish pre-bid attendees to the website? A. Yes, please see Collaboration Portal Q. The drawing appear to be 8 ½ x, where can we get a larger full sized set of the drawings? A. See attached full size pdfs of the contract drawings. I

2 Q5. Will you allow subs to re-visit a few empty apartments? If so when can that be scheduled? A5. Yes. A second pre-bid walkthrough will be held on Wednesday December 8 th at pm. Q. Are vouchers paid for by the Contractor? A. No. Q7. Include full description of patching and painting behind old radiator as required when the new radiator doesn t cover the hole? A7. Damaged wallboard behind radiators is to be repaired with wallboard joint compound and adhesive metal mesh patches whether or not the new radiator covers the damage per Abatement Key Note. Extent of priming and painting in room is between the HA and KBA. Q8. Is cutting and removal of base at new chase wall required? A8. Add the following sentence to Abatement Key Notes,, and 5 on Drawings HM.0, HM.0, and HM.0: "Remove vinyl base that will be covered by enclosure.

The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether the particular rate is a union rate (current union negotiated rate for local), a survey rate (weighted average rate) or a union average rate (weighted union average rate). Union Rate Identifiers A four letter classification abbreviation identifier enclosed

9 Page 7 of 8 /7/0 in dotted lines beginning with characters other than "SU" or "UAVG" denotes that the union classification and rate were prevailing for that classification in the survey. Example: PLUM /0/0. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification, which in this example would be Plumbers. 098 indicates the local union number or district council number where applicable, i.e., Plumbers Local 098. The next number, 005 in the example, is an internal number used in processing the wage determination. 07/0/0 is the effective date of the most current negotiated rate, which in this example is July, 0. Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement (CBA) governing this classification and rate. Survey Rate Identifiers Classifications listed under the "SU" identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SULA //0. SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 0 is the year of survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. 5//0 indicates the survey completion date for the classifications and rates under that identifier. Survey wage rates are not updated and remain in effect until a new survey is conducted. Union Average Rate Identifiers Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 00% of the data reported for the classifications was union data. EXAMPLE: UAVG-OH /9/0. UAVG indicates that the rate is a weighted union average rate. OH indicates the state. The next number, 000 in the example, is an internal number used in producing the wage determination. 08/9/0 indicates the survey completion date for the classifications and rates under that identifier. A UAVG rate will be updated once a year, usually in January of each year, to reflect a weighted average of the current negotiated/cba rate of the union locals from which the rate is based. WAGE DETERMINATION APPEALS PROCESS

10 Page 8 of 8 /7/0.) Has there been an initial decision in the matter? This can be: * an existing published wage determination * a survey underlying a wage determination * a Wage and Hour Division letter setting forth a position on a wage determination matter * a conformance (additional classification and rate) ruling On survey related matters, initial contact, including requests for summaries of surveys, should be with the Wage and Hour Regional Office for the area in which the survey was conducted because those Regional Offices have responsibility for the Davis-Bacon survey program. If the response from this initial contact is not satisfactory, then the process described in.) and.) should be followed. With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to: Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 00 Constitution Avenue, N.W. Washington, DC 00.) If the answer to the question in.) is yes, then an interested party (those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 9 CFR Part.8 and 9 CFR Part 7). Write to: Wage and Hour Administrator U.S. Department of Labor 00 Constitution Avenue, N.W. Washington, DC 00 The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description, area practice material, etc.) that the requestor considers relevant to the issue..) If the decision of the Administrator is not favorable, an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to: Administrative Review Board U.S. Department of Labor 00 Constitution Avenue, N.W. Washington, DC 00.) All decisions by the Administrative Review Board are final. ================================================================ END OF GENERAL DECISION
